stock and at the same time one which is strong and rigid.

Second, to provide a stacking box or tray which is well adapted for usein storage or shipment of small articles or articles which requireshallow trays or boxes to avoid the load which would result from piledup or superimposed articles.

Further objects relating to details and economies of the invention willappear from the description to follow. The inventionis defined andpointed out in the claims.

A structure embodying the features of the invention is illustrated inthe accompanying drawing in which:

Fig. 1 is a top perspective view of a stacking box or tray embodying myinvention with the stacking bails or irons in erected position.

Fig. 2 is an enlarged fragmentary view Lof a corner of the structureshown in Fig. 1 with parts broken away and in section toillustratestructural details.

Fig. 3 is a fragmentary view of a plurality of the stacking boxes ortrays in stacked position within a shipping box or container.

Fig. 4 is an enlarged fragmentary side elevation with the stacking bailin collapsed position at the end of the tray.

Fig. 5 is a fragmentaryperspective view of a modified form or embodimentof my invention. In the embodiment shown in Figs. 1 to 4 inclusive, thebox or tray comprises a bottom I and side walls 2, 2 and end walls 3, 3formed of a single blank or sheet of bendable material such as metal orfibre, the structure illustrated being formed of metal. ner flaps 4lapped upon and secured to the inner sides of the side walls by rivets5. The upper edges of the side walls are rolled outwardly to providebead-like rim portions 5 which embrace the reinforcing rods 1 formed ofwire. These reinforcing rods project at the ends of the rim rolls 6 andare coiled to provide eyes ll.

The end walls 3 have outwardly rolled upper edges providing bead-likerims 8 which are adapted to serve as sockets or bearings for the pintles9, extending inwardly from the arms I!) of the stacking bails or ironsII. The eyes H of the reinforcing rods 1 sustain the major part of thestress on the stacking bails when they are used for handles as is commonpractice, while the The end walls are provided with cor- 7 Claims. (01.220-97) pintles serve as reinforcing members for the end walls. It'willbe noted that they extend to approximately abutting relation as shown inFig. 1.

The load of superimposed boxes or trays is sustained by the reinforcedside walls so that the walls of the box or tray may be formed ofcomparatively light material and at the same time carry heavy loads.

In Fig. 3 I illustrate three of the trays or boxes in stacked relationWithin a shipping container l2.

."The longitudinal ribs [3 of the stacking irons or bails are downwardlyoffset so that the bottom of one box or tray is supported within theupper end of the lower box or tray and lateral shifting movementprevented.

In the modification shown in Fig. 5 the side and end walls [4 and I5 areoffset outwardly at 16, the outwardly offset portions ll thereofreceiving the downwardly facing channel-shaped rim portions l8. Theserim portions have their ebs l9 conformed to receive the pintles and Ireinforcing rods 2|.

. The rim members are secured by means of rivets 22. it is desired toprovide a still stronger or more, rigid structure or where the wallstock is such that it does not permit effective rolling to form thebead-like rim portions, for example when formed of fibre. Metal rimmembers l8 are then employed.

I have illustrated and described my invention in highly practicalembodiments thereof. I have not attempted to illustrate or describeother embodiments or adaptations which I contemplate, as it is believedthat this disclosure will enable those skilled in the art to embody oradapt my invention as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A stacking box or tray comprising, a bottom and side and end wallsformed integrally of bendable sheet stock, the end walls having cornerflaps disposed upon and secured to the inner sides of the side walls,the upper edges of the walls being rolled outwardly to provide bead-likerim portions, reinforcing rods arranged in the rim portions of the sidewalls to project therefrom and terminating at each end in eyes, thebeadlike rims of the end walls constituting pintle bearings aligned withthe openingsof said eyes, stacking bails provided with arms at theirends terminating in inturned pintles disposed through said eyes andextending into bearings, said pintles These rim members are used Where.

coacting to provide reinforcing members for the rim of the end walls andextending substantially the full length thereof.

2. A stacking box or tray comprising, a bottom and side and end wallsformed integrally of bendable sheet stock, the end walls having cornerflaps disposed upon and secured to the inner sides of the side Walls,the upper edges of the Walls being rolled outwardly to provide bead-likerim portions, reinforcing rods arranged in the rim portions of the sidewalls to project therefrom and terminating at each end in eyes, theheadlike rims of the end walls constituting pintle bearings aligned withthe openings of said eyes, stacking bails provided with arms at theirends terminating in inturned pintles disposed through said eyes andextending into bearings.

3. A stacking box or tray comprising, side and end walls formed ofbendable sheet stock, the upper edges of the walls being rolled toprovide bead-like rim members, reinforcing rods arranged in the rims ofthe side walls to project therefrom and terminating at each end in eyes,the rims of the end walls constituting pintle bearings aligned with thesaid eyes, stacking bails provided with arms at their ends terminatingin inturned pintles disposed through said eyes and extending intobearings, said pintles coacting to provide reinforcing members for therim of the end walls and extending substantially the full lengththereof.

4. A stacking box or tray comprising, side and end walls formed ofbendable sheet stock, the upper edges of the walls being rolled toprovide bead-like rim members, reinforcing rods arranged in the rims ofthe side walls to project therefrom and terminating at each end in eyes,the rims of the end walls constituting pintle bearings aligned with thesaid eyes, stacking bails provided with arms at their ends terminatingin inturned pintles disposed through said eyes and extending intobearings.

5. A stacking box or tray comprising, side and end walls formed of sheetstock and having outwardly offset upper edges, reinforcing rim membersof channel section embracing the outwardly ofiset portions of saidwalls, and having their web portions conformed to provide bead-likerims, reinforcing rods arranged in the beads of the side walls toproject therefrom and terminating at their ends in eyes, the beads ofthe end walls constituting pintle bearings aligned with said eyes, andstacking bails provided with pintles disposed through said eyes andextending into said bearings.

6. A stacking box or tray comprising, side and end walls formed of sheetstock, reinforcing rim members of channel section embracing the upperedges of said walls, reinforcing rods arranged in the rim members of theside walls to project therefrom and terminating at their ends in eyes,the beads of the end walls constituting pintle bearings aligned withsaid eyes, and stacking bails provided with pintles disposed throughsaid eyes and extending into said bearings.

7. A stacking box or tray comprising, side and end walls formed of sheetstock and having tubular reinforcing rims, reinforcing rods arranged inthe rims of the side walls to project therefrom and having eyes at theirends, the rims of the end walls constituting pintle bearings alignedwith said eyes, and stacking bails provided with pintles disposedthrough said eyes and extending into said bearings.
